Given the unnormalized table below, answer the following questions step-by-step in the given order. Note that capital letters (A, B, ) represent attribute names and lower-case letters their values.

A	B	C	D	E	F
a	b	c h	d i	e j	f k
l	m	h	d	e	f
n	o	c r	i s	j e	k f

a) Bring the table into the first normal form (1NF).

b) Now, identify all functional dependencies on the table which is in 1NF and determine all the candidate keys.

c) Bring the table into the second normal form (2NF).

d) Bring the table(s) into the third normal form (3NF).

e) Then, determine all primary and foreign keys for each table obtained in part (d).

f) Finally, draw the complete ER-diagram
